The invention further relates to a dry mortar formulation comprising said cellulose ether composition. Furthermore, the invention is directed to a method of improving the slip resistance of a dry mortar formulation without deteriorating the mechanical strength and the open time of the cured dry mortar formulation.Type: ApplicationFiled: May 12, 2011Publication date: November 17, 2011Inventors: Lars FENGLER, René Kiesewetter

Publication number: 20110057434Abstract: An image destruct material comprises a release layer positioned between an image receiving layer and a base layer. The adhesion between the release layer and the base layer is greater than adhesion between the release layer and the image receiving layer. The release layer material can be used in secure documents that have an image receiving layer. After information is printed on the image receiving layer, an overlaminate is applied over it. Removal of the overlaminate destroys the printed image on the receiving layer because of the relative adhesive properties of the image receiving layer, overlaminate and release layer.Type: ApplicationFiled: November 15, 2010Publication date: March 10, 2011Inventors: Daoshen Bi, Tung-Feng Yeh, Robert L. Jones, Brian C. Labrec

Patent number: 7772300Abstract: A polymeric composition consisting of water-soluble or water-swellable copolymers containing sulfo groups and nonionic polysaccharide derivatives, such as methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), methylhydroxyethylcellulose (MHEC), methylhydroxypropylcellulose (MHPC) and welan gum or diutan gum, and the use thereof as an additive in aqueous construction systems based on hydraulic binders, such as cement, lime, gypsum or anhydrite, is described. The composition can also be used in water-based paint and coating systems. The composition according to the invention exhibits a synergistic improvement of the properties and, when used in relatively small amounts, constitutes highly effective water retention agents in such construction and paint systems, which also achieve outstanding air pore stability and tack.Type: GrantFiled: March 16, 2005Date of Patent: August 10, 2010Assignee: Construction Research & Technology GmbHInventors: Michael Schinabeck, Stefan Friedrich, Uwe Holland, Peter Gâberlein, Manfred Schuhbeck

Patent number: 7728055Abstract: An object of the present invention is to provide a new granulating process which can recover desired coagulated latex particles with a significantly excellent yield, and can suppress secondary coagulation under the condition having a higher temperature than a softening point of a polymer, without deteriorating the original quality of the polymer itself. A process for producing coagulated latex particles which can suppress the secondary coagulation under the condition having the broad temperature range, without deteriorating the original quality of the polymer itself by spraying or dropping a polymer latex into a gas-phase containing an inorganic salt and/or an acid, and a dispersant in an aerosol form, and dropping or feeding the droplets of the polymer latex into an aqueous phase containing a dispersant.Type: GrantFiled: July 12, 2006Date of Patent: June 1, 2010Assignee: Kaneka CorporationInventor: Takashi Ueda

Publication number: 20100036024Abstract: Polyolefin dispersions, froths, and foams and articles manufactured therefrom are disclosed. Also disclosed is a method for generating a thermoplastic foam from an aqueous dispersion. The aqueous dispersion may include a thermoplastic resin, water, and a stabilizing agent. The method may include adding at least one frothing surfactant to the aqueous dispersion to form a mixture, adding a flame retardant and/or a phase change material, frothing the mixture to create a froth, and removing at least a portion of the water to produce the foam.Type: ApplicationFiled: October 25, 2007Publication date: February 11, 2010Applicant: DOW GLOBAL TECHNOLOGIES INC.Inventor: Bruce Menning
